Title: Rotary fluid machine
Inventor: IKOMA MITSUHIRO
IPC: F04C18/344
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce a slidingly movable part load on the tip of a vane, lengthen the service life by enhancing reliability, and attain high efficiency by reducing a sliding motion loss by fitting the vane whose tip is brought into close contact with a cylinder inside surface and which forms a suction chamber and a delivery chamber, in a vane groove carved toward a columnar shaft from an outer periphery of a piston so as to freely go in and out. SOLUTION: A crank part 25 eccentric by a prescribed quantity (e) is arranged in a tip part of a rotary shaft 24 of a motor-driven element composed of a rotor 22 and a stator 23. The crank part 25 is rotatably connected through a crank bearing 28 arranged in a central part of a piston 27 eccentrically arranged in a cylinder 26. The piston 27 is not fixed to a rotary shaft 24. A vane groove 29 is arranged in parallel to a rotary shaft L in the piston 27, and a vane 32 whose tip is brought into close contact with an inside surface of the cylinder 26 and which forms a suction chamber 30 and a compression space 31, is fitted in it so as to freely go in and out. Therefore, a slidingly movable part load on the tip of the vane 32 is reduced, and the service life is lengthened by enhancing reliability, and high efficiency can be attained by reducing a sliding motion loss.

Title: Semiconductive pressure converting element and fluid pressure detector
Inventor: NISHIDA MINORU
IPC: G01L9/00
Filed: 1985-08-21
Abstract: PURPOSE:To make it possible to obtain a pressure converting element having a strong structure, high sensitivity and high reliability, by bending a semiconductor diaphragm inward toward a depression with external pressure to generate strain in a semiconductor strain gauge. CONSTITUTION:A pressure detector is mounted at the opening of a container receiving a high pressure fluid of which pressure must be detected or at the opening of the conduit of said fluid. When the pressure of the fluid is applied to a pressure converting element 26, a semiconductor diaphragm 50 and the holder 38 thereof equally receive pressure. The diaphragm 50 does not deform because the peripheral edge part thereof is strongly supported by a support surface 48 but the central part thereof facing a depression 44 is distorted to the inside by pressure and strain gauges 62, 64 receive tensile stress by internal stress while strain gages 66, 68 receive compression stress to change resistance. Therefore, if constant voltage is preliminarily applied to terminal electrodes 70, 74, the equilibrium of a bridge circuit is broken and the potential difference between terminal electrodes 72, 76 changes in according to the pressure of the fluid. This potential difference is picked up to be subjected to amplifying processing by an electronic circuit part and a signal is outputted to a measuring apparatus.

Title: Method for reliquefying gas using cryogenic heat of low temperature liquefied gas
Inventor: FUKUHARA TSUGUKAZU
IPC: F25J1/02
Filed: 1986-08-04
Abstract: PURPOSE:To reduce the cost of equipment by directly heat-exchanging low temperature liquefied gas in a heat storage tank storing heat storage liquid, to accumulate cryogenic heat and feeding generated gas into the heat storage tank to reliquefy it by means of the accumulated cryogenic heat. CONSTITUTION:Low temperature liquefied gas stored in a storage tank 2 is fed to a heat storage tank 16 through a liquid delivery pump 4, and is heat- exhanged by a heat exchanger 17 for absorbing cryogenic heat disposed in the heat storage tank 16. The cryogenic heat is absorbed into heat storage liquid 18, so that the low temperature liquefied gas rises up near delivery temperature. On the other hand, gas generated in the storage tank 2 is fed into the heat storage tank 16 through a compressor 10, then, by means of the cryogenic heat held by the heat storage liquid 18, the gas is condensed into liquid so as to be fed back to the storage tank 2. Therefore, both heat-exchanger of the low temperature liquefied gas with the heat storage liquid, and the gas to the heat storage liquid, can be performed in the heat storage tank 16, hence rendering it possible to make the equipment compact and reduce the cost thereof.
